2. Connect the power cord to the AC line outlet. Press the power switch ○ — on
the front panel to power on, the screen will light up. A few seconds later, a trace
will appear on the screen.
3. Align the trace with the horizontal center line of the graticule by adjusting the

4. Connect the probe to the Y Input terminal and apply the 0.5Vpp CALIBRATOR
signal to be probe tip.
5. Set the AC/DC/

switch to the AC state. A square waveform will be displayed
on the screen.
6. For signal viewing, set the Volts/DIV switch and Time/DIV switch in appropriate
positions so that signal waveform is displayed clearly.

Probe Compensation
When connect the probe with the input channel for the first time, make this
adjustment to match the probe with the input channel. The probe which is not
compensated or presents a compensation deviation will result in the measuring
error or mistake. For adjusting the probe compensation, please carry out the
following steps:
1. Set the switch in the probe to 10X. (see "Set the Probe Attenuation Coefficient"
on P9).
2. Connect the probe BNC connector to the Y Input terminal. Connect the probe
tip to the calibration signal on the front panel (see 11 of Figure 3- 1 Front panel).
Connect the reference wire clamp to the ground wire connector of the
calibration signal (see 12 of Figure 3- 1 Front panel).
3. Check the displayed waveforms and regulate the probe till a correct
compensation is achieved (see Figure 3- 3 and Figure 3- 4).
